She's 22. She's on £18k. Her family are also on low salaries.
She's just taken out her first credit card to build a credit score in order to get a car loan. She's been given a £3k limit on the CC. The intention being to make small purchases and pay the bill off in full each month.
She's now decided she's going to spend £1600 of that £3k on 2 Taylor Swift tickets that her younger sister "needs".
She does not have any savings at all.
I've tried graphs, helping her understand interest and trying to get her to visualise the car as a need and Taylor as a want. I've told her that she'll likely be paying off over years, but nothing is getting through.
Any advice?
